임베디드 기기와 무선 네트워크 기술이 발전함에 따라 PDA나 휴대폰과 같은 모바일 기기 상에서도 멀티미디어 컨텐츠를 소비하는 것이 가능하게 되었다. 그러나 모바일 기기 특성상 무선 네트워크를 통한 컨텐츠 소비환경은 유동성이 강하다. 따라서 모바일 환경에서 멀티미디어 컨텐츠를 효과적으로 제공하기 위해서는 상황에 따른 가용적인 모델이 필요하다. 미디어 형식 변환(Media Transmoding)은 네트워크, 하드웨어, 스트리밍 서버 등의 상황에 따라 능동적으로 컨텐츠의 형식을 변환하여 전송하는 기술이다. 본 논문에서는 모바일 환경에서의 미디어 형식 변환 모델을 제안하고, 자체 개발한 미디어 형식 변환 시나리오를 사용하여 TV-AnyTime Phase 2 Part 3와 SOAP과 결합하여 설계 및 구현하였다.
